UNITED n STATES PATENT OFM .mman w. MARBLE Ami me E. emerse, 'or weerelimineren, Efira@ 1,oc5,i52.

ington, in the county of Franklin and State of Maine, have invented newand useful- Im-y provements in Pumps, of lwhich thev following is aspecification. f l

This invention relates to improvements 1n ,pumps and has particularapplication to def Vices of the character set forth which are carried bya motor' vehicle and operated from the flywheel of the motor `of suchvehicle for initiating tires and other purposes.`

In carrying out the present invention, it is our purpose to `provide apump of the character. described which may be rendered operative andinoperative at the will ofthe operator of the vehicle and whereby thetires of such vehicle may be inflated thereby obviating the necessity ofresorting` to "the common hand pump and inconvenience incident thereto.

It is also our purpose to vprovide a pump which will embody initsconstruction the desired features of simplicity, efficiency,durability and convenience and which may be manufactured and marketedatl a relatively lowcost. 1

Furthermore, we aim to provide a pump which will embrace amongv otherVfeatures a base plate pivoted between its ends upon the motor vehicleand carrying adjacent to one end a pump cylinder andA adjacent to theother end a driving wheel disposed in proximity to the iiy wheel ofthemotor, means acting to hold the driving wheel normally out ofengagement with the fly wheel,

and means being provided for swinging the base plate about its pivot toplace the driving wheel in engagement with the motor fly means.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts hereina-fter'setforth in andfalling within the scope of the claims.

In the accompanying drawings; Figure 1 is a fragmentary sectional viewthrough `a motor vehicle equipped with our improved pump. Fig. 2 is afront -elevation of the A same. is a top` plan view of the pump removedfrom the vehicle, and`Fig. 4 is a side elevation partly in section ofthepump.

Formed in -thekhead 9 'and 'comvmunicatin withfhe' valve seat 10 isa diag-fl onal -air in et passage 15adaptedf'whienthe Aair'inlet valve'isv op'en or disengagedv from eyits'sea't, to' permitrtheintake of airt'o the 90 cylinder under theaction of "the i'pi'ston" therein. Also 'formed' in the-head" 9 fadjafs.cent to the valve seatis a` disch'arge'jbore" 16 and threaded into such`diseharge'b'oreis a tube 17 equipped at its free' end-with afip'- 95 ple18 towhich' may be' connected one end i of an air'h'osehaving itsfreeendwequippel with-- a suitable form of connector'by means ofwhich-the hose may beconnct'ed to one of the tires ofthe vehicle therebyenabling the'air to be lpumpedv 'or'forcedinto such tire, a piston19beingmountedjwithin thelcylinder for 'reciprocation therein andvhaving apiston rod20 extending outwardly of and through the closed end7 v"of ,the tube.

The parts' just" described -fare 44n'iu'nted upon or carried by one endof thebase plate 3, 'while thefopposite end of the plate is preferablyforked orbifurcated asshown moreclearly in Fig. 2, and journaled in the110l arms of the forked or bifurcated end of .the

vbase 'plate are' a pair of spaced parallel y equipped wit shafts 21,22, the former having keyed to one extremit thereof a driving wheel 23 asuitable friction band 24 on the periphery thereof and disposed inproximity to the iy wheel of the motor and adapted to be placed in andout of drlving engagement with such fly wheel, while the relativelyopposite end of the shaft 22 1s uipped with a crank disk 25 to the p1n26 :f which is fastened'one extremity of a pitman 27, the free end ofthe latter beino' connected to the piston rod as at 28. n the presentinstance, the shaft 22 is driven from i the shaft 21 through the mediumof apinion 29 keyed upon the shaft 21 intermediate the arms of thebifurcated or forked endf of the base plate, and a gear similarly keyedupon the shaft 22 and meshing with the pinvion 29. From thisconstruction, yit will be seen .that when the driving wheel 23 yis indriving en agement with fly wheel B of the 'notor of t e vehicle, areciprocating motion will be imparted to the pump piston within thecylinder 5, through the medium of the shaft 21, pinion 29, gear 30,shaft 22, and the crank disk and pitman 25 and 27 respectively. On theintake or suction stroke of f the piston 19, the inlet valve 11 opensunder '.verse movement of the the action of the piston whereby air 1sdrawn into the cylinder and upon the repistom1k such inlet valverisclosed and the air forced through the hose to the tire.

By pivoting the base plate between its ends and mounting the pumpcylinder and piston u on the base plate 1 on one side of the pivot, andthe driving means of the piston at the opposite side of the pivot shaft,we obtain an approximately equal distribution of the weight on the baseplate, so that such plate may be swun about the pivot shaft with easeand fac1lity to place the driving wheel in and out of driving,engagement with the fly wheel. The driving wheel is normally held awayfrom the fly wheel or out of driving engagement therewith and for thispurpose an arcuate shaped arm 31 has one end rigidly fastened to thepivot shaft 2 by means of a set screw or the like 32 immediatelyadjacent the bracket 4, while the opposite end thereof terminates in abearing lug 33 extending beneath the adjacent end of the base plate 3and in the pgth of lmovement lthereof and adapted to 55,

engaged thereby. Interposed between the base plate 3 and the arm 31 andconnected i at its opposite ends to such base plate and armrespectively,is a helical contractile s ring 34 acting normally to swing the base pate about the pivot shaft and disengage the `driving Awheel of the pumpfrom the motor iy wheel,- the bearing lug 33 formzing astop and limitingthe movement of fthe base plate under the action of the spring. ',lhliswhenl the pump and its associated parts are not otherwise affected, suchpump is inoperative due to the spring 34 acting upon the base plate tohold the driving wheel out of engagement with or away from the fly Wheelof the mot-or.

To render the pump operative, thatk is, place the driving wheel of thepump in engagement with the fly wheel, any suitable mechanism may beemployed, in the present instance, we have shown a system of leversincluding a horizontally disposed lever 35 pivoted as at 36 between itsends to a bracklt 37 depending from the under side of the body of thevehicle, one end of the lever 35 being pivotally connected as at 38 to alink 39 having the free end thereof pivoted as at 40 to the end of thebase plate 3 opposite from the driving wheel of the pump, while theopposite end of such lever 35 has pivotally connected thereto as at 41 apedal rod 42 formed with a pedal 43 disposed within convenient reach ofthe foot of the operator upon the vehicle seat. Thus, when the rod 42 isdepressed under the action of the pedal, the lever 35 is swung about itspivotal connection with the bracket 37 and'through the link 39 impartsmovement to the base plate 3 to place the driving Wh'eel of the pump inengagement with the fly wheel of the motor.

From the foregoing description taken in connection With the accompanyingdraw-- ings, the construction, mode of operation and manner of employingour invention will be readily apparent. While we have herein shown anddescribed one particular embodiment of our invention by way ofillustration, it is to be understood that we do not confine ourselves tothe precise details of construction herein described and delineated, asmodification and variation may be made within the scope of the claimsand without departing from the spirit of the invention.
